Why Choose the ABB DS201C40APR30 RCBO?
The ABB DS201C40APR30 is a compact and highly reliable 1P+N residual current circuit breaker with overcurrent protection (RCBO) designed to protect single-phase circuits against overloads, short circuits and residual earth fault currents. As part of the proven ABB DS200 / DS201 RCBO range, it combines residual-current and overcurrent protection in a single two-module device for residential, commercial and industrial electrical installations.
This RCBO provides a 40 A rated current, C tripping characteristic and 30 mA Type A residual-current sensitivity. Its APR high-immunity characteristic provides increased resistance to unwanted tripping caused by transient disturbances, helping maintain continuity of service while providing dependable protection against sinusoidal AC and pulsating DC residual currents.
With a 6 kA rated short-circuit capacity, the DS201C40APR30 provides comprehensive protection for single-phase final circuits in a compact DIN-rail format. Its 1P+N configuration, Type A APR residual-current protection and robust ABB design make it suitable for distribution boards where electrical safety, space efficiency and improved immunity to nuisance tripping are required.

Reliable Protection for Single-Phase Circuits
RCBOs such as the ABB DS201 combine miniature circuit breaker and residual-current protection functions in a single device. This enables the DS201C40APR30 to disconnect a circuit in response to overloads, short circuits and hazardous residual currents while reducing the number of separate protective devices required in a distribution board.
The APR characteristic provides enhanced resistance to unwanted tripping while retaining Type A residual-current protection against sinusoidal AC and pulsating DC residual currents. This makes the DS201C40APR30 particularly suitable for installations where continuity of service is important and transient disturbances could otherwise cause unnecessary circuit interruptions.
Typical Applications
- Residential electrical distribution boards.
- Commercial building final circuits.
- Industrial single-phase auxiliary circuits.
- Socket outlet and general power circuits.
- Lighting and building services circuits.
- Single-phase loads requiring enhanced immunity to unwanted tripping.
